Definitions

the invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 12.
a device of this type and a method are known for example from DE 103 27 276 A1 known, which goes back to the registration xin.
the known device comprises a shut-off or gout flap, which is used to regulate the loading of a blast furnace with coke and Möller.
the device comprises a flap plate, which is movable to close or open the bottom opening of a material bunker arranged above the gout of a blast furnace in an open position or closed position.
a drive mechanism is usually hinged to the flap edge, whereby it is achieved that the flap plate in the open position, the flow opening substantially completely free.
the flap plate is relatively far away from the opening, so that the gout of the blast furnace must be dimensioned accordingly to avoid collision of the flap plate with bulk material.
the guidance of the flap plate along the curved paths causes in the region of the opening a relative movement between the edge region of the flap plate and the valve seat provided for the sealing seat on the bottom opening.
a relative movement parallel to the opening plane is detrimental and can lead to premature wear of the sealant.
the invention has for its object to improve a device of the type mentioned specifically such that a simple maintenance low-maintenance operation is made possible, in particular, a premature wear of the sealing system should be avoided.
the invention also has the object of specifying a blast furnace with such a device and a method for closing or opening an opening, in particular bottom opening of a material bunker arranged above the gout of a blast furnace.
this object is achieved with regard to the device by the subject of claim 1.
the object is achieved by the subject matter of claim 11 and with regard to the method by the subject-matter of claim 12.
the invention is based on the idea of providing a device for closing or opening an opening of a material bunker arranged above the gout of a blast furnace with a drivable flap plate, which can be moved into an open position releasing the opening and a closed position blocking the opening and vice versa.
the flap plate is connected to a gear arrangement such that for the flap plate in the region of the opening, a linear movement is substantially perpendicular to the opening plane and distal of the opening pivotal movement feasible.
the invention has the advantage that a relative movement transversely to the flow direction or in the opening plane is practically avoided by the linear movement of the flap plate. Due to the resulting reduced friction when placing or lifting the flap plate wear of the sealant is reduced, so that there is less maintenance. At the same time, the compact design of the Gag be maintained as the flapper plate performs a pivotal movement distally of the opening and thus is guided close to the opening or of the corresponding housing.
the pivoting movement of the flap plate at least in the overlapping region of the flap plate with the opening, a translational movement parallel to the opening plane, which is superimposed on a rotational movement. This ensures that the flapper plate is moved out of the region of the opening without removing it too far in the flow direction from the opening in order to avoid a collision with bulk material.
the gear assembly comprises a four-bar chain which couples the flap plate with a drive.
a gear arrangement allows in a structurally simple and robust way, the linear movement of the flap plate in the region of the opening and the pivotal movement distally of the opening.
the gear assembly may include an actuating lever and a plate lever having fixed and spaced from each other arranged axes of rotation.
the actuating lever and the plate lever may be coupled by a first pivot.
the plate lever may include a first arm rigidly connected to the flapper and a second arm rotatably supported by one of the axes of rotation, the first and second arms being coupled by a second pivot.
the first and second pivot joints are arranged in the closed position on a common vertical axis. This is achieved in a simple manner an exclusively translational movement of the flap plate perpendicular to the opening plane and, associated therewith, a plane-parallel lifting or placing the flap plate.
the fixed axes of rotation can be offset relative to a vertical axis.
the axis of rotation of the plate lever closer to a central axis of the Opening be arranged as the axis of rotation of the actuating lever.
the staggered arrangement of the axes of rotation results in different pivoting radii for the two levers, so that in a simple manner an optimized movement path of the flap plate is effected close to the housing of the opening or the material bunker.
the first and second pivot joints may be movable on different pivoting paths, wherein the pivot joints in the open position are spaced further apart than in the closed position. This also ensures that the flap plate distal to the opening performs a close to the housing of the opening guided movement, wherein in the vicinity of the opening or in the region of the opening is a linear movement of the flap plate.
the device is claimed in connection with a blast furnace and a method for closing or opening the opening of a material bunker arranged above the gout of a blast furnace.
the Figures 1 - 4 show a Gichtklappe with a flap plate 12, which is provided for closing or opening a bottom opening 10 of a arranged above the gout of a blast furnace material bunker 11.
a flap plate 12 By opening the flap plate 12 is bulk material, in particular ores and Möller through the bottom opening 10 in the gout of the blast furnace ( Fig. 2 ).
the bottom opening 20 In the closed position, the bottom opening 20 is gas-tight closed by the flap plate 12 ( Fig. 1 ).
the bottom opening 10 is arranged on the underside of a funnel 23, which is connected to the material bunker 11.
a sealing seat 24 is provided with sealing elements at the opening edge.
a corresponding sealing surface 25 is provided, which cooperates sealingly in the closed position of the flap plate 12 with the sealing seat 24.
the flap plate 12 is in a closed position ( Fig. 1 ) and into an open position ( Fig. 2 ), wherein the flapper plate 12 is arranged in the open position in a space between the funnel 23 and the housing of the gout 26 and thus outside the fluid flow.
the gear arrangement 13 is adapted such that the flap plate 12 in the region of the bottom opening 10 performs a linear movement substantially perpendicular to the opening plane and distal of the bottom opening 10 a pivoting movement.
the pivoting movement is especially in Fig. 3 to recognize.
the linear movement of the flap plate 12 in the region of the bottom opening 10 means that the flap plate 12 is moved linearly, at least as long as it is in contact with the bottom opening 10, specifically with the sealing seat 24. During this movement process, any relative movements in the opening plane, ie transversely to the flow direction S, are critical due to the friction wear caused thereby. By inventively enabled linear movement of the flap plate 12, this is avoided. This means that the placement and pressing of the flap plate 12 on or to the sealing seat 24 and the release of the contact pressure and the lifting of the flap plate 12 from the sealing seat 24 by an exclusively translational movement perpendicular to the opening plane. The flap plate 12 is thus plane-parallel to the opening plane, ie to the plane which is spanned by the bottom opening 10 moves. Only then, ie if there is no contact between the flap plate 12 and the sealing seat 24 and any relative movements transverse to the flow direction S are not critical, the flap plate 12 is pivoted laterally and moved into the space between the hopper 19 and gout housing 26
the adapted for this movement of the flap plate 12 gear assembly 13 is according to the embodiment that in the Figures 1 - 4 is constructed as follows. Other gear arrangements are conceivable which allow a linear movement of the flap plate 12 in the region of the bottom opening 10 connected to a pivoting movement distally of the bottom opening 10.
the gear arrangement 13 comprises a four-bar linkage or a four-link swivel linkage. This allows a particularly compact and robust design of the gear arrangement
the gear assembly 13 comprises two levers, in particular an actuating lever 15 or generally a drive lever and a plate lever 16 or generally a steering lever.
the actuating lever 15 is formed in a cranked design and has two L-shaped sections, which are arranged on both sides of the funnel 19 and the bottom opening 10 ( Fig. 4 ).
the two L-shaped sections of the actuating lever 15 are connected to each other, so that overall results in a combined UL-shape of the actuating lever 15, as in the FIGS. 1 and 4 to recognize.
the actuating lever 15 engages in the closed position the flap plate 12, wherein the connecting part between the two L-pieces of the actuating lever 15 eccentrically with respect to the flap plate 12 is arranged ( Fig. 1 ).
the plate lever 16 is U-shaped and engages under the flap plate 12.
the plate lever 16 is fixedly connected to the flap plate 12 and forms a rigid unit with this. In this case, the plate lever 16 engages the center of the flap plate 12, whereby a centric introduction of the contact force in the flap plate 12 and thus a uniform contact pressure is achieved.
the actuating lever 15 and the plate lever 16 are rotatably supported respectively by fixedly arranged axes of rotation 17, 18.
the axes of rotation 17, 18 are spaced apart from each other, wherein the axis of rotation 18 of the plate lever 16 is provided below the axis of rotation 17 of the actuating lever 15.
the two axes of rotation 17, 18 are arranged offset to one another and relative to a vertical axis, wherein the axis of rotation 18 of the plate lever 15 is arranged closer to the center line M of the bottom opening 10 as the axis of rotation 17 of the actuating lever 15th
the actuating lever 15 has a first pivot 19, which is arranged in the closed position at the same height as the axis of rotation 17 of the actuating lever 15.
the rotary joint 19 and the axis of rotation 17 are each arranged in the region of the shorter leg of the L-shaped section of the actuating lever 15.
the rotary joint 19 is arranged on the center line M of the funnel 23 or the bottom opening 10.
the hinge 19 connects the actuating lever 15 articulated to the plate lever 16.
the connection of the two L-shaped parts of the actuating lever 15 on both sides of the bottom opening 10 and thus the combined UL-shape of the actuating lever 15 is advantageous. This makes it possible, as in Fig. 4 shown to provide the drive 14 only on one side of the gear assembly 13.
the plate lever 16 has a first arm 20 and a second arm 21, wherein the first arm 20 is rigidly connected to the flap plate 12.
the first arm 20 is U-shaped, as in FIG Fig. 4 illustrated and coupled on both sides of the bottom opening 10 by a second pivot 22 with the second arm 21 articulated.
the second arm is rotatably supported by the fixedly arranged axis of rotation 18 and connected to the housing.
gear assembly 13 shows that the mounted by the stationary axis of rotation 18 second arm 21 opposite disc lever 16 is shorter than that in the closed position according to Fig. 1 arranged parallel to the short legs of the L-shaped portion of the actuating lever 15th
the two hinges 19, 22 are arranged with respect to the bottom opening 10 spatially variable
the gear assembly 13 is formed on both sides of the bottom opening 10 substantially analog.
Fig. 3 represents in discrete steps the spatial movement of the flap plate 12 and the associated lever mechanism, the end points of the movement by the closed position of the flap plate 12 on the one hand ( Fig. 1 ) and its open position ( Fig. 2 ) are defined.
